What Causes Hip Impingement?

Legg-Calve-Perthes Disease

Legg-Calve-Perthes disease is a condition that occurs in childhood and can lead to hip impingement. When a child is growing, the two major parts of joint of the hip are the socket and ball, or acetabulum and femoral head. Legg-Calve-Perthes disease, also simply known as Perthes disease, is a hip condition of childhood in which the femoral head collapses due to loss of blood supply. Upon this occurrence, all or part of the area involved dies temporarily. The socket is not affected, only the ball. While the child's body absorbs those dead bone cells and then replaces them with new, the disease can leave the ball deformed, leading to disability.
